GEORGE A. STACKHOUSE, OF OAKLAND, CALIFORNIA, ASSIGNOR TO L. A. YOUNG SPRING AND WIRE CORPORATION, OF DETROIT, MICHIGAN SPRING STRUCTURE FOR BED BOTTOMS AND THE Application led April 12,

The main object of this invention is "to provide a spring bed bottom which is well adapted for use or embodiment in wall beds, diy beds, folding beds, davenports and the li e.

Objects pertaining to details and econo 'mies' of my invention will definitely appear from the description to follow. The invention is defined in' the claims. y

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing in which: l

Fig. 1 is a plan view of a spring bed bottom structure embodying the features of my invention.

Fig. 2 is a fragmentary side view.

Fig. 3 is. an enlarged fragmentary plan View.

In the embodiment illustrated I provide a main frame comprising end pieces 1 and side rails 2 secured to the end pieces to form a rigid frame. In the embodiment illustrated the side rails are formed of pipe or tubing having flattened portions 3 at their ends to receive the rivets 4. The central portions 5 of these side rails are downwardly offset, the offsets extending throughout a substantial portion of the length of the sided rails.

I provide a central spring unit consisting ao of the helically coiled body springs 6 mount- A ed on the cross bars 7 these cross bars having upwardlyoifset hangers 8 at their ends secured to the'upper sides of the side rails as by the rivets 9. The lower ends ofthe springs .6 are secured to4 these cross bars by means of the tie wires 10 which have loops 11 therein engaged with the bottom coils 12 of the springs 6 and with the supporting bars 7, as clearly shown in Figs. 2 and 3. The top Coils of the springs 6 are connected by coiled springties 13. y

This central body unit is complemented by the end bottom units 14 consisting in the embodimentillustrated of bordery frames andlongitudinal and cross wires 15 and 16 providing a supporting grid. These endbottom members are supported from the frameend members by means of the horizontally disposed helically coiled springs 17 and to the upwardly offset end portions of the side rails 1929.

by means of the coiled springs 18. The end rows of body springs are connected to these end bottom members by means of the coiled springs 19.

At each side I provide side bars 20 in the form of rods having eyes 21 at their ends, these rods being connected to the side rails by coiled springs 22 andJ the hooks '23, the hooks being engaged in holes 24 in the end portions of the side rails. These side bars are secured to the side body springs by means of clips 25.

I thus secure a very resilient bed bottom with room at the ends to receive the mechanism of a folding bed, wall bed and the like. At the same time the structure presents a resilient surface throughout.

I have not attempted to illustrate and describe the various adaptations of my improvements which are ossible as I believe this disclosure will ena le those skilled in theart to embody or adapt the same as may be desired. l

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a spring structure, the combination with a main frame comprising end members and side rails, said side rails having downwardly offset central portions, cross bars having upwardly offset hangers at their ends se- `cured to the downwardly ofet portions of said side rails, upright helically coiled body springs mounted on said vcross bars, grid-like end bottom members disposed between said body springs and the main frame end members and comprising border frames and longitudinal end cross members, coiled supporting springs for said bottom members secured to their border frames and to said main frame end members and the end portions of said side rails, coiled spring ties connecting the top coils of the saidl body springs to each other and the end rows of body springs to said bot` tom member'border frames, lside bars dis posed above the said downwardly offset portions of saidside rails and secured to the top coils of the outer side rows of said body springs, andl coiled springs connecting the `ends of said top side bars to the end portions of said side rails.

2. In a spring structure', the combination lwith a main frame comprising end members and side rails, said side rails having downwardly offset central portions, cross bars having upwardly offset hangers at their ends secured to the downwardly offset portions of said side rails, upright helically coiled body springs mounted on said cross bars, grid-like end bottom members disposed between said body springs and the mainframe end mem bers and comprising border lframes and .longitudinal end cross members, coiled supporting springs for said bottommembers secured to their border frames and to said main frame end members and the end portions ofv said side rails, and coiled spring ties connecting the top coils of the said body springs to each other and the end rowsof body springs to said bottom member border frames.

3.4In a spring structure, the combination with a main frame comprising end members and side rails, said side rails having downwardly odset central portions, cross bars mounted on the vdownwardly oii'set portions of said side rails, upright helically coiled body' springs mounted on said cross bars, end bottom members disposed between said body springs and the main frame end members, horizontally disposed coiled supporting springs for said bottom members secured to said main frameend-members and the end portions of said side. rails, ties connecting the top coils of the said body springs to each other and the end rows of body springs to said end bottom members, side bars disposed tions of said side rails, a central body spring unit comprising upright body springs mounted. on said side rails, the outer 'side body springs beingsecured to said sidebars,

end bottom members disposed between said .l

body unit springs and the end bars of the frame, supporting springs for said end bottomunit's secured to said frame end bars and -to the upwardly offset ends of said side rails,

and spring ties connect-ing said'bodyy unit i spring to each other and the end body unit springs to said bottom members.'

6. In a spring structure, the combination. with amain frame comprising end members and side r'ails'having upwardly offset end portions secured to said end rails, said bars*v provided with supporting springs at their ends secured tosaid upwardly oi'set end por'- tions of said side rails, a central body spring unit comprising upright body springs hand. f
